In some flowers, a purple pigment is synthesized from a red precursor pigment. In the absence of all pigment, flowers are white. A pure-breeding plant with red flowers was crossed to a pure-breeding plant with white flowers. All of the F 1 plants had white flowers. The F 1 plants were crossed to each other, and the F 2 consisted of 165 plants: 123 with white flowers, 32 with purple flowers, and 11 with red flowers. How do these results suggest that flower color is determined

Recessive epistasis

Explanation:

Epistasis is a gene interaction it influences a phenotype. Genes can mask each other effect with one been dominant over the other or they can both be expressed to produce a new trait.

It is the conditional relationship between two genes that can determine a single traits. When there are two alleles that dictate phenotypes they can affect one another such that allele of one gene is recessive to one that is a dominant allele over the other.

A recessive epistasis occur when a recessive allele mask the expression of both recessive and dominant allele of another locus. Allele for white color mask the effect of other alleles expressing itself over them to give a phenotypic ratio of 9:3:4 a deviation from normal mendelian principle.

When a dominant allele masks the effect of both dominant and recessive alleles at another locus, it is a dominant epistasis.

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c

explanation:

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less

hope i even just a little : )
